Secure Application-Aware Service Differentiation in Public Area Wireless Networks

We are witnessing the increasing demand for pervasive Internet access from public area wireless networks （PAWNs）. As their popularity grows, the inherent untrusted nature of public places and the diverse service requirements of end users are two key issues that need to be addressed. We have proposed two approaches to address these issues. First, the Home-based Authentication Protocol （HAP） that provides a framework by which to establish trust between a nomadic client and a service provider using a trusted third party （home）. Second, we argue that the best-effort-based service model provided by many access points is not enough to satisfy the end user fairness and to maximize the wireless link utilization for a diverse user population. We have proposed an application-aware service differentiation （AASD） mechanism that takes both application semantics and user requirements into consideration. Our analysis of this framework shows several fruitful results. The total authentication latency increases with the number of clients but at a rate that is much less than linear increasing latency. Also, in comparison with two other bandwidth allocation approaches, the best effort and static access control, our proposed application-aware service differentiation method, outperforms them in terms of the client fairness and wireless bandwidth utilization.

Residents'Satisfaction with Public Services in Mountainous Areas:An Empirical Study of Southwestern Sichuan Province,China

Enhancing the efficiency of public services is essential to residents in mountainous areas. It is also important to promote sustainable development of these regions. Analysing residents' satisfaction with public services in mountainous areas can help in evaluating outcomes of fiscal investment and identifying potential coping approaches for improving public service efficiencies. The residents' satisfaction with public services and the factors that influence such satisfaction were examined in this study. A study of 12 towns located in the southwestern Sichuan Province was performed using an entropy-weighted analytic hierarchy process(EWAHP), the technique for order preference by similarity to ideal solution(TOPSIS) and Tobit regression methods. The results indicate that: 1) the spatial distribution of satisfaction with public services is non-uniform, and the spatial distribution structure varies for different types of public services. 2) Residents' satisfaction with public services is influenced by both objective and subjective factors. Population density, economic distance, social and cultural divisions and elevation are the major objective factors, whereas bounded rationality, the hierarchy of needs and service expectations are the main subjective factors. The most effective strategies for enhancing residents' satisfaction with public services are likely to be clustering the population, choosing supply centres with different public services, regulating the cultural division in ethnic minority towns, selecting supply priorities in accordance with residents' needs, implementing targeted intervention policies and establishing ‘bottom-up' and ‘top-down' integrated decision-making mechanisms.

Public choice on coordinated development of border regions and its empirical research:a case study of Wuling mountain area

Due to the difficult segmentation of land destiny, popularity destiny, industry destiny on the platform of common interests demand, the regional governance of production and living for the needs of the people in cross-regional areas, such as in the aspects of security, education, assignment and management of water resources, transportation, energy, environment protection and public health, the administrative border regional cooperation is relatively easy. These aspects are equivalent to public products. Just because of this, it leads to problems that nobody will not control. The governments, in order to realize regional economic coordinated development and to eliminate the regional interests parties of administrative regions economy in microcosmic, were adapting various self-protection measures, even including that "you may have your policy but I have my countermeasures" that is derived from inter-regional economic relations. The action of market segmentation has limited the flow of various economic development elements, especially the condition of "dead end highway", resource exploitation and use, difficult social security work in social living of the administrative boundary zone. This paper studies the typical economical district of Wuling mountain area in the obvious strategic position at the junction of Chongqing, Guizhou, Hunan, Hubei provinces from the angle of regional public management and public choice to present issue awareness and academic purpose.

Use of a Public Fishing Area Determined by Vehicle Counters with Verification by Trail Cameras

This study was performed in order to determine visitation at remote areas that would be unaffordable due to logistic reasons. Four TrafxTM vehicle counters, each programmed with different settings, were placed along the lone access road to remotely sense the daily use activities and count accuracy at the New Underwood Lake Public Water Access Area. Use was corroborated during daylight hours with game cameras. Data was stratified between weekdays/weekends due to differences between the two periods. Two counter settings, threshold and delay, were best when set at a value of 8, but a value of 16 for delay provided almost equal results. Overall, there were 38 counts of use per day for a total of 2318 over the 61 day period. This study demonstrated how vehicle counters, in combination with game cameras for verification, can aid managers for determining use in remote access areas. Future work may lead to identifying details for producing a surrogate to traditional angler use surveys.

Demand of Rural Public Goods in Western Ethnic Minority Areas

In the context of Development of the West Regions and the construction of new countryside,on the basis of defining the concept of public goods,this article analyzes the status quo and layers of demand of rural public goods in western ethnic minority areas:the demand of rural public goods in ethnic minority areas shows "pyramid" structure,that is,the most basic layer is production-based rural public goods,followed by life-based rural public goods and democratic-management-based rural public goods.Finally the countermeasures for achieving effective demand of rural public goods are put forward as follows:adhere to customers(farmers)-oriented principle;innovate upon the rural residents' demand expression mechanism of public goods in ethnic minority areas;achieve diversification of supply subject of rural public goods in ethnic minority areas.

Currency Areas: Public Debt, Inflation and Unemployment

Can public debt, inflation and unemployment tell us something about optimal or not optimal currency areas? In this paper, I compare the behavior of these variables in two countries, Mexico and the United States of America (USA), along with the member countries of the Euro Zone (European Monetary Union, or EMU). The main purpose is to know the divergence between public debt, average inflation ﹣0% in the graphs—in the main cities or regions of the first two, and compare them with the countries of the EMU. The period of 2001-2012 is chosen to be the years in which the Euro has been circulating among member countries of the Monetary Union (EMU). We find significant differences that allow us to determine the faults that the criteria of divergence on these variables had on the founding treaty of the European Monetary Union.

Innovation of Adult Education Supply in Rural Areas from the Aspect of Rural Public Goods——A Case Study of Quzhou City,Zhejiang Province,China

Status of rural adult education in Quzhou City is analyzed from three aspects of supply main body,supply method and fund source.Problems in the rural adult education in Quzhou City are pointed out.Firstly,the top-down supply decision model can not fully meet the needs of farmers.Secondly,education resources can not be best allocated.Thirdly,both rural labor force market and employment service are not perfect.In order to promote the development of rural adult education,the education supply mode of rural adults should be established,which is "supplied by the government,coordinated by the government,participated by the society,operated according to market mechanisms".This needs to set up the leading position of government,to establish the pattern of diversified main bodies of adult education supply in rural areas,and to construct the market operation mechanism driven by interests.

The Importance of Environmental English Public Signs to Xiong’an New Area’s Ecological Environment in China

With the establishment and development of Xiong’an New Area in China, more foreign industries and visitors will be attracted to come here. Investigations made in our study show that the environmental English public signs are very important. They can offer directions for foreigners who can’t understand Chinese well because they have these three functions: indication, suggestion and prohibition. In order to help Xiong’an New Area play its “eco card”, the translators are supposed to attach great importance to the translation of environmental English public signs.

根据地公营工业企业化、民主化生产管理制度的形成(1927—1949)

中国共产党领导的根据地公有制工业发源于土地革命根据地时期。初期在战斗频繁的条件下主要实行军管制。随着生产的发展和管理问题出现,如何处理工厂内的各种关系问题凸显,随即苏维埃政府颁布相关条例予以规范。抗日根据地时期,在相对稳定的条件下,根据地公营工业在改善管理上做了多种探索,致力于改善生产并调动多方面人员的积极性。解放战争时期,公营工业的管理体制进入完善时期,在企业化和民主化相结合的管理体制下,工人的地位在中国历史上第一次被充分肯定,最终形成了独具特色、人民性显著的中国特色的“两化”工业管理模式。

粤港澳大湾区食品安全社会共治

以粤港澳大湾区为研究对象,基于计划行为理论构建公众参与食品安全治理影响因素的理论模型。描述性统计分析发现粤港澳大湾区食品安全治理的公众参与存在地区差异,即珠三角地区公众参与、主观规范、知觉行为控制、对政府监管的满意度低于港澳地区。随后通过结构方程模型分析揭示了公众参与食品安全共治的影响因素和机制,结果显示食品安全治理中政府监管满意度对公众参与有显著影响,其作用机制是通过正向影响主观规范、参与态度、知觉行为控制对公众参与产生正向影响。食品受害经历对风险感知和参与态度有正向影响,进而促进食品安全治理的公众参与,即有食品受害经历的个体参与食品安全治理的意愿更高。研究结论对促进粤港澳大湾区食品安全跨界合作与社会共治具有重要参考意义。

数字政府建设是否促进省级共同富裕?——基于城乡基本公共服务均等化门槛效应研究李鹏1,丁洲2,范静2

基于2016—2021年27个省级行政区的面板数据,采用固定效应回归模型、门槛模型、空间滞后模型及量化分析方法,考察数字政府建设促进共同富裕度的线性关系、门槛效应、空间溢出效应,结果发现:数字政府建设可以促进省级共同富裕度且具有区域异质性;城乡基本公共服务均等化对数字政府建设促进省级共同富裕度具有显著的非线性门槛关系,当城乡基本公共服务均等化水平达到门槛值后,其对数字政府建设促进省级共同富裕度才具有正向影响;数字政府建设促进共同富裕度具有显著的空间溢出效应,能显著提升相邻省份的共同富裕度。数字政府建设除了促进经济发展提高共同富裕度外,更重要的是实现社会公正和发展共享的关键作用;城乡基本公共服务均等化水平制约着数字政府建设和省级共同富裕度的成效发挥;要善于使用数字政府建设促进共同富裕的空间溢出效应,同相邻省份共同实现区域数字政府建设水平提升,一同实现共同富裕。
